Hmmm, in my opinion pyro and huntsman should be first (for the buffs). Than add scoundrel or hydro depending on your feels(heal might be more useful early on tho), because that is useful for whole game. I would add warfare only after you find enrage skillbook, you have small use for that otherwise.
After huntsman 4 (that means 2 points from you, and rest should be from gear probably), I would just max ranged and then scoundrel or warfare (depending if you want higher damage overall or higher crits+movespeed).
Dont bother too much with memory, as most skills barely do more damage than your attack (especially when enraged), so only use skills with some extra value (cc, buffs). Of course add as much as you need, just dont over do it (you gain 1 slot every 2 levels). Instead of skills use your arrows and scrolls.
